Abstract
Description
Technical Field
[0001] This utility model relates to the field of FPC flexible circuit board testing technology, and in particular to a suction-pull separation device for FPC flexible circuit board separation testing. Background Technology
[0002] Flexible printed circuit boards (FPCs) refer to circuit boards made using flexible materials as the substrate. These circuit boards can be freely bent, folded, and even twisted without affecting their electrical performance. Multilayer FPCs, on the other hand, are a more complex technology developed based on single-layer or multi-layer rigid boards. They are formed by stacking and connecting multiple layers of flexible circuit boards in a specific way to create a unified structure. This approach increases the density and complexity of the circuit board while maintaining the advantages of flexible boards.
[0003] In most designs, the layers of a multilayer FPC circuit board are bonded together. However, in some specific application areas, in order to meet specific functional requirements, multilayer FPC circuit boards with partially separated states are designed to meet market demands.
[0004] After the multilayer FPC circuit boards are produced, the separated areas still need to be tested to improve product quality and prevent unseparated products from being released. However, because the spacing between the FPC circuit boards in each layer of the multilayer FPC circuit board is very small and normally quite tight, it is difficult to visually distinguish whether the FPC circuit boards in each layer are completely separated.
[0005] Therefore, it is necessary to propose a new technical solution to address the above problems. Utility Model Content
[0006] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the aforementioned problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a suction-pull separation device for FPC flexible board separation and detection, comprising a drive module and an adsorption element;
[0008] The first adsorption component is connected to the first drive module. The first drive module drives the first adsorption component to move toward the multilayer FPC flexible board and adsorb the surface FPC flexible board. Then, the first drive module drives the second adsorption component to move away from the multilayer FPC flexible board and pull the surface FPC flexible board to separate it.
[0009] As a further embodiment of this utility model: it is characterized in that a second drive module is also provided, which is installed opposite to the first drive module, and the second drive module is connected to an adsorption component.
[0010] The second driving module drives the second adsorption component to move toward the multilayer FPC flexible board and adsorb the surface FPC flexible board. Then, the second driving module drives the second adsorption component to move away from the multilayer FPC flexible board and pull the surface FPC flexible board to separate it.
[0011] As a further embodiment of this utility model: the present invention includes a driving module three, a driving module four, and a clamp one and a clamp two arranged opposite to each other, wherein the driving module three is connected to the clamp one, and the driving module four is connected to the clamp two.
[0012] The clamps one and two are used to clamp the two ends of the multilayer FPC flexible board, while the adsorption components one and two are respectively arranged opposite to each other and facing the opposite sides of the multilayer FPC flexible board between the clamps one and two.
[0013] The drive module three and drive module four respectively drive clamp one and clamp two to move closer or further apart, so that the multilayer FPC flexible board between clamp one and clamp two forms an arch shape or a flat state.
[0014] As a further aspect of this utility model, the adsorption element one and the adsorption element two are connected to a vacuum generator via a pipe.
[0015] As a further aspect of this utility model, the vacuum generator is characterized by being connected to a filter.
[0016] As a further aspect of this utility model: the adsorption element one includes a suction rod one and a suction nozzle one;
[0017] The second adsorption component includes a second suction rod and a second suction nozzle; and both the first suction rod and the second suction rod are retractable.
[0018] As a further embodiment of this utility model: the suction rod includes a sleeve rod with an opening at one end, a spring is provided inside the opening of the sleeve rod, and a telescopic rod is movably connected inside the opening of the sleeve rod, and the telescopic rod is connected to the spring.
[0019] As a further embodiment of this utility model, both the first and second suction nozzles are made of flexible soft rubber.
[0020] Compared with existing technologies, the beneficial effects of this technical solution are as follows: When performing separation testing of multilayer FPC flexible boards, the part of the multilayer FPC flexible board to be tested is pushed into an arch shape and placed opposite to the first adsorption component. Then, the first drive module causes the first adsorption component to suck up the surface FPC flexible board on the concave side of the testing part. Subsequently, the first drive module drives the first adsorption component to pull the surface FPC flexible board upward, separating the surface FPC flexible board from the testing part. Then, the suction force of the first adsorption component is released, and the multilayer FPC flexible board is flipped over. The other side of the testing part is pulled and separated using the same principle. This allows for a direct understanding of the separation between the upper and middle layers, and between the lower and middle layers, helping operators to better observe the separation status of the multilayer FPC flexible board. This is convenient, fast, and improves testing efficiency.
[0021] Furthermore, by adding the drive module and the second adsorption component, the other side of the multilayer FPC flexible board can be fixed when one side is pulled during the two pulling and separating processes, thus preventing the detection part from being pulled.
[0022] By setting up drive module three, drive module four, clamp one and clamp two, the two ends of the multi-layer FPC flexible board can be clamped during the pulling and separating process, and the arching can be performed to make the detection part naturally form an arch shape, reducing manual operation and further improving work efficiency.

Detailed Implementation
[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figures 1-3 A suction-pull separation device for FPC flexible board separation and detection includes a drive module-1 and an adsorption element-2.
[0032] Adsorption component 2 is connected to drive module 1. Drive module 1 drives adsorption component 2 to move toward the multilayer FPC flexible board and adsorb the surface FPC flexible board. Then, drive module 1 drives adsorption component 6 to move away from the multilayer FPC flexible board and pull the surface FPC flexible board to separate it.
[0033] Specifically, when performing separation testing of multilayer FPC flexible boards, the part of the multilayer FPC flexible board to be tested (hereinafter referred to as the "test part") is placed in a position opposite to the adsorption member 2. Taking the position directly below the adsorption member 2 as an example, the drive module 1 drives the adsorption member 2 to move towards the test part, so that the adsorption member 2 picks up the surface FPC flexible board of the test part. Then, the drive module 1 drives the adsorption member 2 to move upward, and the adsorption member 2 pulls the surface FPC flexible board upward, so that the surface FPC flexible board is separated from the test part. This allows for a more intuitive understanding of the separation status of each layer of FPC flexible board in the test part.
[0034] For the separation test of three-layer FPC flexible boards, one side can be faced with the adsorption component 2 first, and then pulled apart using the above operation. Then, flip it over and face the other side with the adsorption component 2 and pull apart again. This two-stage pulling and separation operation separates the surface FPC flexible boards of opposite sides of the three-layer FPC flexible boards from the test part, thus providing a direct understanding of the separation between the upper and middle layers, and between the lower and middle layers. When the adsorption component 2 is pulled apart twice, if the separated FPC flexible board is a single layer, the separation is qualified. If the separated FPC flexible board is a double or triple layer, the separation is incomplete. This method is convenient and quick, improving the testing efficiency.
[0035] Furthermore, when performing the two pull-separation tests mentioned above, it is preferable to push the test section of the multilayer FPC flexible board into an arch shape, and then make the concave surface of the arch shape face the adsorption member 2. After the adsorption member 2 picks up the surface FPC flexible board on the concave surface, it pulls in the opposite direction, so that the arch shape of the surface FPC flexible board and the arch shape of the test section form a reverse bow, thereby making the separation degree between the surface FPC flexible board picked up by the adsorption member 2 and the test section greater, so as to further help the operator to better observe the separation state of the multilayer FPC flexible board. The local stress of the arch shape itself can also prevent the adsorption member 2 from directly pulling the entire test section.
[0036] In one embodiment of this utility model, a second drive module 5 is also provided, which is installed opposite to the first drive module 1. The second drive module 5 is connected to an adsorption member 6. The second drive module 25 drives the adsorption member 26 to move toward the multilayer FPC flexible board and adsorb the surface FPC flexible board. Then, the second drive module 25 drives the adsorption member 26 away from the multilayer FPC flexible board and pulls the surface FPC flexible board to separate it.
[0037] Specifically, when performing two separation tests, taking the detection part facing downwards (i.e., towards the adsorption component 2 6) to form an arch shape as an example, drive module 2 5 moves adsorption component 2 6 towards the detection part, so that adsorption component 2 6 adheres to and fixes the arched surface of the detection part. Then, drive module 1 moves adsorption component 2 towards the detection part, so that adsorption component 2 adheres to the upper FPC flexible board on the concave surface of the detection part. Then, drive module 1 moves adsorption component 2 away from the detection part, so that adsorption component 2 pulls the upper FPC flexible board on the concave surface of the detection part to separate it. Similarly, the suction force of adsorption component 2 and adsorption component 2 6 on the detection part can be released, and adsorption component 2 and adsorption component 2 6 can be returned to their original positions by drive module 1 and drive module 2 5, forming the detection part into an upward-facing (i.e. towards adsorption component 2) arch shape. Through the same principle operation as above, the lower FPC flexible board on the other side of the detection part can be pulled and separated.
[0038] The effect is that when the detection section forms an arch shape and the surface FPC flexible board on the concave side is pulled apart, the other end of the detection section, which is the arched end of the arch shape, can be subject to a fixed suction force. This further prevents the entire detection section from being pulled along during the process of pulling the surface FPC flexible board on the concave side, thus preventing the surface FPC flexible board on the concave side from being pulled apart individually. Furthermore, when the detection section forms an arch shape in one direction, the arched end has the stress of the arch. When the surface FPC flexible board on the concave side is pulled in the opposite direction, the stress of the arch plus the suction force of the arched end will prevent the other layers of FPC flexible boards from being pulled apart, thus further ensuring that each FPC flexible board pulled apart is a single layer (based on the condition that the FPC flexible boards are in a completely separated state).
[0039] In one embodiment of the present invention, there are a third drive module 9, a fourth drive module 10, and a first clamp 11 and a second clamp 12 arranged opposite to each other. The third drive module 9 is connected to the first clamp 11, and the fourth drive module 10 is connected to the second clamp 12.
[0040] Clamp 11 and clamp 2 12 are used to clamp the two ends of the multilayer FPC flexible board, while adsorption component 1 2 and adsorption component 2 6 are respectively arranged opposite to each other and facing the opposite sides of the multilayer FPC flexible board between clamp 11 and clamp 2 12.
[0041] Drive module 3 9 and drive module 4 10 respectively drive clamp 1 11 and clamp 2 12 to move closer or further apart, so that the multi-layer FPC flexible board between clamp 1 11 and clamp 2 12 forms an arch shape or a flat state. The multi-layer FPC flexible board between clamp 1 11 and clamp 2 12 is the detection part. Clamp 1 11 and clamp 2 12 are both composed of a placement plate and a clamp cover hinged to the placement plate. The non-detection parts at both ends of the multi-layer FPC flexible board are placed on the placement plate, and then the clamp cover is flipped to clamp the non-detection parts.
[0042] Specifically, during the two-stage pulling and separating of the multilayer FPC flexible board, in the first pulling and separating, drive module three 9 and drive module four 10 respectively drive clamp one 11 and clamp two 12 to move closer to each other, so that the detection part between clamp one 11 and clamp two 12 naturally forms a downward-facing arch shape. Then, drive module two 5 drives adsorption component two 6 to move towards the detection part, so that adsorption component two 6 picks up the lower end of the detection part, that is, the arched end of the arch shape. Then, drive module one 1 drives adsorption component one 2 to move towards the detection part, so that adsorption component one 2 picks up the upper layer of FPC flexible board in the detection part. The upper FPC flexible board, i.e. the concave surface, is then subjected to suction by the second adsorption component 6. The driving module 1 moves the adsorption component 2 away from the detection part, causing the adsorption component 2 to pull the upper FPC flexible board away from the detection part. After the first pulling separation is completed, the adsorption components 2 and 6 release the suction on the detection part. The driving module 3 9 and the driving module 4 10 move the clamps 11 and 2 12 away from each other, causing the detection part to be straightened. Then, the second detection is performed. The detection steps are the same as the first principle, i.e., forming an arch upwards to detect the pulling separation of the lower FPC flexible board. This will not be elaborated further here.
[0043] By clamping the multilayer FPC flexible board with clamp 11 and clamp 22, and driving the drive module 39 and drive module respectively to drive clamp 11 and clamp 22, the separation and testing of multilayer FPC flexible boards can be facilitated. It can ensure that the multilayer FPC flexible board remains stable during the pulling and separation process, and the non-testing part of the multilayer FPC flexible board is clamped. It can also prevent the entire multilayer FPC flexible board from being deformed when the testing part is pulled, protect the non-testing part from being affected, and reduce manual operation, further improving work efficiency.
[0044] Preferably, before the drive module three 9 and drive module four 10 respectively drive the clamp one 11 and clamp two 12 to move closer together and form an arch shape in the detection part, that is, when the separation part is in a flat state, drive module one 1 drives the adsorption member one 2 to first contact and hold one side of the detection part, or drive module two 5 drives the adsorption member two 6 to first contact and hold the other side of the detection part; while drive module three 9 and drive module four 10 respectively drive the clamp one 11 and clamp two 12 to move closer together to push the detection part into an arch shape;
[0045] By driving module 1 to move adsorption component 2 away from the detection part in a synchronous manner, a pulling force is applied to the detection part; or by driving module 2 5 to move adsorption component 2 6 away from the detection part in a synchronous manner, a pulling force is applied to the detection part. In this way, the direction of the arch can be controlled during the formation of the arch shape in the detection part, so as to achieve the effect of controlling the formation direction of the arch shape in the detection part during the two pulling and separating operations.
[0046] In this solution, drive module 1, drive module 2, drive module 3, and drive module 4 can all be composed of a servo motor, a slide rail, a lead screw, and a slider. The slider is slidably connected to the slide rail, the lead screw is located inside the slide rail, and the slider is screwed to the lead screw. The servo motor drives the lead screw, causing the slider to slide inside the slide rail, thereby moving the adsorption component 2, adsorption component 6, clamp 11, and clamp 212.
[0047] In an embodiment of this utility model, the first adsorption element 2 and the second adsorption element 6 are connected to a vacuum generator 13 via pipes; the vacuum generator 13 is connected to a filter 14.
[0048] Specifically, the vacuum generator 13 is used to generate a vacuum suction force between the first adsorption element 2 and the second adsorption element 6, thereby enabling the first adsorption element 2 and the second adsorption element 6 to adsorb the surface of the multilayer FPC flexible board. The vacuum generator 13 can quickly generate and release vacuum, which is suitable for occasions that require frequent switching of adsorption states in this case. The filter 14 is used to remove impurities and moisture from the compressed air to ensure that the air entering the vacuum generator 13 is clean. Clean air can reduce the contamination inside the vacuum generator 13 and extend the service life of the vacuum generator 13.
[0049] Preferably, the first suction component 2 includes a suction rod 3 and a suction nozzle 4; the second suction component 6 includes a suction rod 7 and a suction nozzle 8; and both the first suction rod 3 and the second suction rod 7 are telescopic. The first suction rod 3 includes a sleeve rod 301 with an opening at one end, a spring 302 is provided in the opening of the sleeve rod 301, and a telescopic rod 303 is movably connected in the opening of the sleeve rod 301, and the telescopic rod 303 is connected to the spring 302. Similarly, the second suction rod 7 has the same structure as the first suction rod 3, which will not be described in detail here.
[0050] Specifically, taking suction rod 3 and suction nozzle 4 as examples, when suction nozzle 4 contacts the multilayer FPC flexible board and is subjected to pushing or pulling force, the telescopic rod 303 will move in and out of the sleeve rod 301. The elasticity of the internal spring 302 can prevent suction nozzle 4 from applying excessive pressure or pulling force to the multilayer FPC flexible board, reducing the risk of damage caused by excessive pressure or pulling force. This allows suction nozzle 4 to gently contact or pull the surface of the multilayer FPC flexible board, reducing scratches and avoiding the risk of mechanical damage such as tearing.
[0051] More preferably, both nozzle 4 and nozzle 8 are made of flexible soft rubber, specifically silicone material;
[0052] Specifically, silicone has excellent softness, which allows nozzle 4 and nozzle 8 to make gentler contact with the surface of the multilayer FPC flexible board, thereby further reducing the risk of mechanical damage such as scratches and tears.
[0053] Among them, this utility model is as follows Figure 1 The device also includes a tooling plate, a vertical plate, and a mounting bracket. The mounting bracket can be used to install and fix the drive module 1, drive module 2, vacuum generator 13, and filter 14, while the vertical plate is used to install and fix the drive module 3, drive module 4, and drive module 10.
[0054] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
